Detective Comics #452

After Batman fails to prevent a gold-coin theft and its perpetrators' escape, this proves to be the first in a wave of crimes carried out by highly specialised crooks. Realising an organisation must lie behind the crimewave, Batman embarks on a bold plan. Infiltrating the set-up - the Crime Exchange, an agency providing the right crook for the right crime - he allows himself to be captured so as to make contact with the Exchange's secret President. Claiming to be a reporter disguised as the Batman, he's given a test: pick up and fire a gun, something the REAL Batman has sworn never to do.
